Electric force between point charges
18.3What the syllabus asks of you
- understand that, for a point outside a spherical conductor, the charge on the sphere may be considered to be a point charge at its centre
- recall and use Coulomb’s law F = Q1Q2 / (4πε0 r²) for the force between two point charges in free space
